The W3C typically describes web services as: "a piece of software that is designed to support machine-to-machine interoperability over a network. With the rapid expansion of functionally similar web services over the internet exposes a great challenge for users to identify the web service origin and integrity process. A traditional centralized web service registry drastically shifts the dynamic power of web services, by establishing a platform for service provider‟s to advertise their self-contained, self-reliable and self-governing data. Though, these centralized infrastructures do not offer easy way to explore available services for users in thenetwork, and also nor have the ability to verify their origin and history. The contribution of the paper is to address these challenges by leveraging the decentralized, immutable, tamper-proof Blockchain technology by establishing Blockchain service registry and execution via smart contract for secured semantic web service discovery. This allows users to explore the services in a network and also able to identify its service origin and integrity. Our first evaluation shows the promising results with this system paradigm in the field of web service provisioning. [ABSTRACT FROM AUTHOR]

In a Plug-in hybrid vehicle, it is possible to get the required propulsion for the vehicle with more than one power source. This improves the performance of the vehicle and reduces energy loss. The Battery, Fuel cell, Ultracapacitor, Solar cell are the multiple energy source can be used in PHEV. This modern intelligent transport system is support to reduce the usage of fossil fuel and CO2 emission. The rule-based algorithm is used for optimizing the power flow between the traction motor and power source. The supervisory control strategy was verified through MATLAB simulation circuit. The technique has proved the improved performance of the vehicle and extended range of travel. [ABSTRACT FROM AUTHOR]
